MIC4720 3mm X 3mm 2.0MHz 2A Integrated Switch Buck Regulator

The Micrel MIC4720 is a high efficiency PWM buck (step-
down) Regulator that provides up to 2A of output current.
The MIC4720 operates at 2.0MHz and has proprietary
internal compensation that allows a closed loop bandwidth
of over 200KHz.
The low on-resistance internal P-Channel MOSFET of the
MIC4720 allows efficiencies over 92%, reduces external
components count and eliminates the need for an
expensive Current Sense resistor. By Micrel Semiconductor
